Fertility preservation

Fertility Preservation : the mothers of tomorrow

This is a technique which allows the reproductive capacity of a woman to be preserved when reaching a more mature age or when having to undergo treatments which could diminish her fertility.


Fertility preservation in 7 questions

1. Who are the women it is intended for?

All women who cannot have a family at present and whose fertility may be diminished in the immediate future, either due to age or illness and its treatments.

2. Is it recommended in cases of cancer?

Some tumours (for example, breast cancer) and some autoimmune diseases can be cured by chemotherapy, but these medications often damage ovules (oocytes) causing a significant reduction of the woman’s fertility, sometimes causing total sterility.

We therefore insist on the importance of vitrifying (freezing) the ovules before beginning the treatment, so that the woman can achieve pregnancy with her own ovules once cured of the illness.

3. Up to what age can I preserve my fertility?

Nowadays, social, economic and work reasons increasingly lead us to delay the age of first pregnancy. We are well aware that from 35 years of age the fertility of a women rapidly diminishes, and it is therefore recommended to vitrify the ovules before 35-38 years of age. In this way, the woman will have her own ovules in the following years, and thereby practically maintain fertility.

4. How does preservation of fertility work?

There are different techniques, depending on the characteristics of each woman and the reason for preservation. The most commonly used, and the one which has given us the best results, is vitrification of oocytes.

Through a brief hormonal stimulation, ovules are brought to maturity, and then extracted from the ovaries. They are brought to a temperature of -196ºC so that they freeze so fast that the cell is not damaged, thereby preserving practically its full fertilisation potential. For the vitrified ovules, time does not pass; they can maintain their fertility for years after vitrification.

5. Can stimulation with hormones cause cancer?

The treatments used for the preservation of fertility are very short, similar to those of in vitro fertilisation, and do not cause the appearance of tumours. In some cases, when it is not possible to mature the oocytes due to the presence of an advanced tumour very sensitive to hormones, alternative techniques may be selected, such as freezing of the ovarian cortex.

6. Won’t extracting ovules leave me sterile?

Not at all. In each menstrual cycle there are a number of oocytes ready to mature, but only one is obtained and brought to ovulation, while the others are lost. With follicular stimulation, these ovules continue their development and mature to allow their subsequent use.

7. Is preservation of fertility only for women?

The ovule is the most important cell in the process of pregnancy, and it is very sensitive to age and to some medications. Men maintain their fertility for many years longer than women, but sperm cells can also be frozen, especially if the patient has to undergo a treatment which may be toxic for the reproductive cells.

If you wish to be a mother but believe that it is not yet the time, it is highly recommended to periodically undergo a fertility study. It is very simple, consisting only of carrying out an ultrasound to evaluate your ovarian reserve, and a blood analysis. If it is observed that your fertility is starting to diminish, Preservation would be the appropriate action.
